Abstract (en)
One embodiment provides a system that delegates signature production in a CCN. During operation, a first content producing device monitors content objects created by a second content producing device. A content object can be identified by a name that is a hierarchically structured variable length identifier (HSVLI) which comprises contiguous name components ordered from a most general level to a most specific level. The first device retrieves the content objects and authenticates a message authentication code for each content object based on a key shared by the first and second device. The first device creates a manifest with a name and a content object hash value for each content object, produces a digital signature for the manifest based on a private key of the first device, and includes the digital signature in the manifest, thereby delegating signature production to the first device for content objects created by the second device.
